  Structure–activity relationships in a series of C2-substituted gluco-configured tetrahydroimidazopyridines as β-glucosidase inhibitors

  摘要：

  Inhibition of glycoside hydrolases has widespread application in treatment of diabetes, viral infections, lysosomal storage diseases and cancers. Gluco-configured tetrahydroimidazopyridines are the most potent beta-glucosidase inhibitors reported to date. Using transition state mimic strategy, a series of C2-substituted gluco-configured tetrahydroimidazopyridines were designed and synthesized. Compounds 3 (K-i = 0.64 nM) and 5 (K-i = 0.58 nM) showed stronger inhibitory potency against beta-glucosidase. Maestro 9.1 was used to study the structure-activity relationships by docking the compounds into the beta-glucosidase active sites. Crown Copyright (C) 2011 Published by Elsevier Ltd.

  conditions, the synthesis of the imidazoles yielded mostly the gluco-imidazole 19 or a mixture of the gluco/manno epimers 19/20. In contrast to the triazole 4, the isomeric triazole 7 proved a good inhibitor of retaining β-glucosidases from sweet almonds and from Caldocellum saccharolyticum. This observation and the qualitative correlation between basicity and inhibitory power of the tetrahydropyridoazoles

  三唑7和已知的葡萄糖-和甘露聚糖-构型的咪唑10和11是通过在Hg（OAc）2促进的反应中，将肼环与肼-甲醛或氨基乙醛二甲基乙缩醛环合到铝硫代内酰胺14而制备的。取决于反应条件，咪唑的合成主要产生葡萄糖-咪唑19或葡萄糖/甘露糖差向异构体19/20的混合物。与三唑4相反，异构体三唑7被证明是保留甜杏仁和糖化卡尔德氏菌中β-葡萄糖苷酶的良好抑制剂。该观察结果和四氢吡啶并恶唑的碱性和抑制能力之间的定性相关性为（通过部分保留）β-葡糖苷酶的糖苷“侧向质子化”假说提供了进一步的证据。

  observed in glycosidase inhibition have been achieved so far with jack bean α-mannosidase (JBα-man) using iminosugar clusters based on weakly binding mismatching active-site-directed inhibiting epitopes (inhitopes) in the d-gluco series. Here, we synthesize and evaluate as JBα-man inhibitors a series of mono- to 14-valent glycoimidazoles with inhitopes displaying inhibition values up to the range of

  迄今为止，使用基于亚氨基糖簇的杰克豆α-甘露糖苷酶（JBα-man），已在糖苷酶抑制中观察到了最佳的多价作用，该簇基于d-葡萄糖系列中弱结合错配的活性位点定向抑制性表位（抗原决定簇）。在这里，我们合成并评估了一系列单价至14价的糖咪唑类化合物作为JBα-man抑制剂，其抑制位表现出高达数百nMs的抑制值，以研究抑制位亲和力对多价效应的影响。该系列中最有效的抑制剂是14价的甘露咪唑衍生物，可抑制具有纳摩尔Ki值（2±0.5 nM）的JBα-man，观察到的结合增强至多相对较小（化合价最高可达25倍） -更正的基础）。这项研究的结果支持这样一个事实，即JBα-人-抗体的亲和力和抑制性多价作用的强度向相反的方向发展。发现基于糖基咪唑基的抗原决定基对结合情况的主要影响。多数合成的甘露咪唑簇以及14价的葡萄糖咪唑衍生物被证明是JBα-man的紧密结合抑制剂。
